Hello,
clearly having too much time on my hands, I've been keeping track of the MPG my 4Runner is returning, and it makes for worrying reading. I've only had the truck since 01/01/09 and I've done just over 1000 miles in it, which has taken about 4 tanks of diesel. The MPG I've got back off it has gone like this;
27.34 -> 26.62 -> 26.07 -> 25.11
If it carries on dropping for each successive tank of fuel, I'm going to hit zero MPG some time around the middle of October...who knows what happens if it then starts going negative!
Seriously though, why is my MPG dropping off like this? Is it just because I'm getting more used to the truck and I'm driving it harder, do you reckon?
Of the various remedies I can think of, I was hoping people might give their opinions;
New Air Filter : I'm tempted by a K&N filter which just fits into the standard airbox - the adverts all say you'll never need to buy another filter and you get better BHP - most things claiming better BHP lie in my experience, but are these K&N filters worth the money (50.00ish instead of 20.00ish for a standard filter)
Injector/Fuel System cleaning liquids : I've used these before, but never noticed any appreciable change in performance
Fuel Filter : I'm not sure what sort of filter the hilux has, or where it is, but would a new one help at all? I'm not sure this would actually have any effect on MPG, anyway...
Any thoughts or advice would be much appreciated
Thanks,
Paul
